I have a pink thick patch of skin on my scalp ever since I was small, and I have ignored it since. Now that I looked at it again (about 10 years later), I realized it grew. What could this be? It's not itchy, and its pretty wide in and long. Here's a picture of it, as my lack of description is poor: (http://snag.gy/ZxWxS.jpg). Can anyone tell me what this is and will I die? I'm 17 by the way. Thank you!
